Five Parameters

We have data from 1945-2012 of deceased governor candidates in the US. We hope to forecast how long candidates live past the elections. One concern is that lifespans change over time.

\[ lived\_after_i = \beta_0 + \beta_1 male_i + \beta_2 c\_election\_age_i + \\ \beta_3 male_i * c\_election\_age_i + \epsilon_i \]
